The combustion of ethane is expressed in the balanced reaction C2H6 + 3.5O2= 2CO2 + 3 H2O. Given the mass of oxygen gas, we get the moles of ethane needed by converting this mass to mole (dividing my 32 g/mol), then multiply by 1/3.5 (stioch ratio) and the molar mass of ethane (30 g/mol). The answer is 16.69 grams ethane.
These are isotopes of that element. The nucleus is different because the number of neutrons differ and aren't the same. The number of protons are the same though.<span />
Answer:
47.99g
Explanation:
The first step st have a balanced chemical reaction equation.
This is given as;
2Fe + 3Cl2 --> 2FeCl3
From the equation,
2 moles of Fe would react with 3 moles of Cl2.
I mole of Fe = 55.8 (3 s.f) (Molar mass of Fe)
2 mole = 2 * 55.8 = 111.6 g
1 mole of gaas occupies 22.4dm3
3 moles = 3 * 22.4 = 67.2 dm3
1dm3 = 1L
This means 116g would consume 67.2L
Xg would consume 27.8L
x * 67.2 = 27.8 * 116
x = 3224.8/67.2
x = 47.99g (2 d.p)
Answer:
The correct option is option e, both A and C
Explanation:
Ethyl butanoate is an ester. Ester undergoes hydrolysis when heated with water containing dilute acids. Ester hydrolysis gives carboxylic acid and alcohol.
Therefore, ethyl butanoate on hydrolysis gives butanoic acid and ethanol.
Amide also undergoes acidic hydrolysis and yields carboxylic acid and amine.
N-methylbutanamide is an amide. It gives butanoic acid and methylamine when undergoes hydrolysis with H2O in the presence of H2SO4.
Hence, the correct option is option e.
